Taiwan Semiconductor Corporation MBR7150H

Overview

MBR7150H from Taiwan Semiconductor is a 7.5A, 150V AEC-Q101-qualified Schottky barrier rectifier in TO-220AC package, featuring 0.95V forward voltage at 7.5A/25°C, 150A surge capability, and 5°C/W junction-to-case thermal resistance. It serves as a high-efficiency output rectifier in automotive-grade DC-DC converters and industrial SMPS.

For engineers reviewing the MBR7150H datasheet, MBR7150H pinout, MBR7150H application, or MBR7150H equivalent, key selection factors include its 150V V_RRM, AEC-Q101 qualification, TO-220AC mechanical compatibility, and thermal performance under sustained 7.5A conduction.

Technical Context

This single-die Schottky rectifier uses guard ring technology for overvoltage protection and meets JESD201 Class 2 whisker resistance. Its 10,000 V/µs dV/dt rating supports fast-switching topologies without parasitic turn-on.

Designed for operation from −55°C to +150°C junction temperature, it delivers stable reverse leakage ≤5 mA at 125°C and rated VR, with R_θJA = 15°C/W enabling compact heatsink integration in space-constrained power stages.

Key Specifications

Pinout & Package

TO-220AC package: 3-terminal through-hole outline with isolated tab (cathode-connected), matte tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 molding compound, and 0.56 N·m maximum mounting torque.

FAQ

Is MBR7150H pin-compatible with standard TO-220AC rectifiers?

Yes, MBR7150H uses the industry-standard TO-220AC outline with anode, cathode, and isolated cathode-connected tab. Its pinout matches generic TO-220AC rectifiers including Vishay VS-75SQ150 and ON Semiconductor SB7150H, enabling direct mechanical replacement in existing layouts without PCB modification.

What is the maximum allowable case temperature for continuous operation of MBR7150H?

The MBR7150H supports continuous operation up to 150°C junction temperature. With R_θJC = 5°C/W, the maximum recommended case temperature is 135°C when dissipating 3W (e.g., 7.5A × 0.4V), assuming no additional thermal interface resistance between tab and heatsink.

Does MBR7150H require a thermal pad under the tab for reliable operation?

No thermal pad is required for MBR7150H if mounted directly to a bare metal heatsink with proper torque (≤0.56 N·m). However, a thermally conductive but electrically isolating pad is mandatory when the heatsink is grounded and the cathode must remain floating, as the tab is internally connected to the cathode terminal.

How does the guard ring in MBR7150H improve system-level reliability?

The guard ring in MBR7150H suppresses edge avalanche by controlling electric field distribution at the die periphery. This prevents localized hot-spot formation during transient overvoltage events-such as load dump in automotive 12V systems-thereby extending device lifetime and eliminating need for external clamping components in many designs.

Can MBR7150H be used in synchronous rectification topologies?

No, MBR7150H is a passive Schottky rectifier and cannot replace actively controlled MOSFETs in synchronous rectification. It functions as a unidirectional freewheeling or output rectifier only. For synchronous designs, discrete MOSFETs or dedicated SR controllers paired with logic-level FETs are required instead of MBR7150H.
